A method of overlay and sandwich formation of a combination of pervious concrete with itself and/or standard cement concrete wherein the existing surface is cleaned either mechanically or chemically, a coating of cement and water mortar, mixed in a high energy/shear type mixer, is then applied, and pervious concrete is directly applied to any required thickness, which results in a complete bonding between the overlay and the original pavement. To apply pervious concrete to reinforced concrete slab construction, in cases where lateral water movement may be undesirable, a similar procedure is used after transverse penetration of the reinforced slab with holes spaced so as to clear reinforcing steel and of sufficient size and area to permit the drainage of the combined slab. These holes will be filled with pervious concrete during the overlay procedure.
A method of producing a self-adhering pervious concrete product for paving of the type which allows fluids to pass therethrough in combination with an existing strata, said method comprising the steps of:
